Ipayipi elingenamthungo elingu-304 lensimbi engenamthungo ngenxa yengcindezi yokushisa yangaphakathi ebangelwa ukufakwa okushisayo kwepayipi elingenamthungo elingu-304 lensimbi engenamthungo emithungoni ngenxa yama-coefficients ahlukene eso lokunwebeka lapho lishisisiwe likhiqiza ingcindezi enkulu yokushisa, ikakhulukazi ngesikhathi sokushintsha kwezinga lokushisa ngokushesha ngenxa yokushaqeka okushisayo. steel quenching crack kuzoveza into efanayo.

Ekushintsheni kwezinga lokushisa okujwayelekile izikhathi eziningi noma izikhathi ezingamakhulu ukufudumala kuzophinde kukhiqizwe ukukhathala okushisayo.Kodwa njengokushisa okuphezulu nokukhathala, okuklanyelwe emazingeni okushisa aphezulu ngenxa yokuhlukahluka komthwalo wangaphandle okubangelwa, kuyilapho okokuqala kufana noshintsho okushisa okushisa ngenxa yokucindezeleka kwangaphakathi okushisayo okubangelwa ukukhwabanisa.

Ingozi yobunjiniyela yepayipi lensimbi engenalutho engu-304 yensimbi engenazithungo, ngemva kokuhlolwa okukhulu, isifinyezo, ngaphansi kokucindezeleka kwesigaba samapayipi endawo kuphela ukugqwala kokugqwala kwezinto zokusebenza kanye nezingxenye ezisuka ekugqwaleni (ukuqhekeka kokugqwala kwengcindezi nokubhoboza, ukugqwala kwemifantu), futhi akukho ukugqwala okujwayelekile okubalulekile.Ngisho noma ingaphansi kwengcindezi enzima kakhulu yokulimala kokugqwala kwemishini akusahlukile.Kweminye imithombo yezindaba, ngezinye izikhathi kokubili ukugqwala kokucindezeleka okukhulu (noma okuhambisana nokugoba okukhulu), kunokugqwala okujwayelekile okubi kakhulu.
